Carrollite

Unknown Owner
An incredibly good example for the species with a large sharp bright lustrous metallic crystal of carrollite 5.5 cm across on a calcite matrix. The piece is been stabilized where the crystal meets the matrix. Without this stabilization, it is doubtful that the crystal would remain attached to the matrix. As it is, this is very solid and is in outstanding condition. This is about as good as it gets for the species.

Carrollite from Kamoya South II Mine, DR Congo
Kamoya South II is the modern benchmark locality for carrollite. Its best specimens have the look that made the species famous among contemporary sulfide collectors: brilliant silver to steel-gray crystals, often mirror-faced, with crisp spinel-family geometry set into pale calcite or dolomitic carbonate. The visual effect is unusually clean for a sulfide—hard, metallic geometry against light matrix—and the finest examples have enough reflectivity that the faces flash like cut metal when turned under a lamp.
